Bland Altman plots for respiratory maneuvres demonstrating the degree of agreement between the volume estimated by the Kinect to the volume measured by spirometry (Bland and Altman, 1999). (A) Forced Vital Capacity, (B) Forced Expiratory Volume in 1 second, (C) Vital Capacity, and (D) Inspiratory Capacity. ±150 ml has been used as limits of acceptable difference, according to accepted criteria (Miller et al., 2005).
